Symptoms of autism in 3-year-olds

The symptoms of autism in 3-year-old babies are not that obvious. Parents need to observe carefully to know whether their baby is suffering from this disease. If any abnormality is found, they should be taken to the hospital for detailed examination and treatment in time. Otherwise, it will have a great impact on their body and may even cause developmental abnormalities. Therefore, it is necessary to cure it as soon as possible.

1. Alinguistic type: often mistaken for hearing problems or aphasia.

2. Immediate imitation: It is divided into imitation with changes and flexibility, and imitation without changes and flexibility. The former is considered to be autistic children with the intention to express communication; the latter mostly do not have the intention to communicate.

3. Prolonged echolalia: Repeating certain words, phrases, idioms, sentences, entire poems or songs over and over again after a period of time. It can also be divided into communicative or non-communicative, and this behavior is usually related to the situation and stress.

4. Speaking without emotion: There is no real communication.

5. Unable to control tone and volume: When speaking, they are like puppets, very mechanical, unable to express emotions or feelings through the tone, rhythm, and intonation of the voice, and unable to use different volumes in different situations.

6. The meaning of a word cannot change: for example, “学校” and “修改”, their pronunciations cannot be distinguished.

7. Pronoun reversal: There is confusion among pronouns such as “you”, “I” and “he”.

8. Not clear about the concepts of affirmation and negation: often use "no", but rarely use or even never use "yes" or "good".

9. Immature grammatical structure: no grammatical meaning in the usual sense.

10. Rarely ask questions: Apart from the manifestation of compulsive behavior, they rarely ask questions to raise questions.

11. Fixation: Repeating a certain sentence regardless of changes in the situation.

12. Unable to use causal language: such as because, so, therefore, if, etc.

The cause of autism remains unknown, but many researchers suspect it is controlled by genes and triggered by environmental factors. While the role of environmental factors remains unclear, researchers have found seven gene sets that are frequently found in people with autism.

The National Institute of Mental Health conservatively estimates that the prevalence of autism in the United States is one in every 1,000 people. The overall rate of autism in males is three to four times higher than that in females, but the symptoms in females are more severe than those in males. Data released by the United Nations show that the incidence of autism is 1 in 150. The diagnosis is based on a number of psychiatric principles, and there are a number of clinical tests that can assist in making the diagnosis.

Autism is not physically obvious, so diagnosis requires a complete physical and neurological evaluation. According to the Diagnostic and Statistical Manual of Mental Disorders, autism requires delayed development of social interaction, speech, and social communication before the age of three. ICD-10 also requires that symptoms appear before the age of three. Some autistic people can improve their social skills through diagnosis, treatment, internship and special education, and can participate in mainstream education and social activities. However, with the current level of medical technology, it is not possible to completely cure autism.
